Briefing Provided Upon Request

Contact and/or Presenter Information

Contact Person / Presenter: Michael Jankowski, P.E.,  Senior Project Engineer, Public Works Department  

Action Requested
Acceptance of August 2013 20-Year Water Distribution System Master Plan Update ("Master Plan Update").

Enabling/Regulating Authority
Section 163.3177, Florida Statutes, outlines general requirements for comprehensive plan data and elements, including capital improvement and potable water elements.  Computer modeling as part of this Master Plan Update reviewed proposed 5-year capital improvement  projects and identified other potential projects for the 5, 10, and 20-year planning periods.  Modeling and master planning was also performed in accordance with the Comprehensive Plan Supplement #15, Water Supply Sub Element.

Background Discussion

The last master plan update for the Manatee County Water Distribution system was completed in 2003, by Parsons Engineering Science, Inc., covering the 2000-2020 planning period.  Typically, utility master plans are updated roughly every five years, so an update was essentially overdue.  This Master Plan Update covers projected system improvements through 2030, covering typical short-term (five years or less) and long-term (10 years or more) utility master planning periods.  This Master Plan will be used as a guide for the County's potable water capital improvements plan.

The backbone of this Master Plan Update is the system water model maintained by County staff in Public Works.  In order to determine the potential need for future system improvements, model runs were performed under various scenarios to identify existing and projected deficiencies.  For each planning period, the service populations were kept consistent with the County's "How Will We Grow" program and projected water demands provided by the Utilities Department.   The use, maintenance, and calibration of the model will continue to be an on-going process.

A separate analysis was performed to identify the potential costs for the replacement and rehabilitation of aging infrastructure.  Specific projects were not identified under this analysis.

The Master Plan Update was completed entirely in-house by Manatee County Public Works staff while being peer-reviewed by the Engineer-of-Record for the County, Carollo Engineers.
